suffering from an illness or disease or feeling unwell

he was taken ill with food poisoning

a terminally ill patient

even the seriously ill cannot get tests done immediately

poor in quality

ill judgement dogs the unsuccessful

badly, wrongly, or imperfectly

the street is dominated by ill-lit shops

it ill becomes one so beautiful to be gloomy

only with difficulty; hardly

she could ill afford the cost of new curtains

a problem or misfortune

a lengthy work on the ills of society

I shall; I will

I'll arrange it
